| With the development of the geochemistry research, oil cracking experiment becomes onekind of widespread applications of the experiment technology. The most important theory of theexperiment is time-temperature compensate principle. With the aid of the experiment in thelaboratory,we simulated physical and chemistry evolutionary process and obtain the basic data,appraise the hydrocarbon potential, study the process and the mechanism of the hydrocarbon,infer the dynamics of the hydrocarbon pattern..The process of the sediments become hydrocarbon (oil, gas) can be considered as chemicalreaction, therefore, the process relates temperature and the time to chemical reactions, can bedescribed as the chemical kinetic equations.The dynamics model can accurately reflect the oilthermal decomposition process and the microscopic chemistry characteristicThe model also canreflect the characteristic of oil deposit. The sample of the experiment is the Tadong 2nd well oil,the Tazhong 62th well oil and the Xinjiang mixture oil. The experiment system is definited andpressure is considered in, the experiment uses the golden tube as reactor. We design the time andtemperature for the experiment, and then analyze the pressure and apply the data to the chemicalkinetics model, obtain the temperature-productive relations. and apply the corresponding point toundergroud finally.The experiment has discussed the characteristic of methane,ethane,propane and total gaswith the different pressure. The result indicated that temperature is the most effective factor, butalso correlated with time, pressure, crude oil nature. The pressure has the inhibitory action to thetransformation of crude oil to the natural gas.The Suppression is obviously at high temperature.pressure more tremendous influence more obvious, When study natural gas preserved conditionin deep places, the pressure influence is noticeable. Inspected oil cracking dynamics behaviorunder the pressure condition, and demarcated the dynamics parameter.We analyzed three oil types and applied it to hydrocarbon dynamics in research areas, andhave appraised the crude oil cracking intensity. |
